ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 700,838, dated May 27,

Application tiled May 8, 1901. Serial No. 58,617. (No model.)

T0 all whom it may concern:

Be it known that I, Crans JAY SELTZER, a

citizen of the United States, residing at Phi1 adelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Atomizers, of which the following is a specification, reference being had to the accompanying drawings, in whichu Figure 1 is a longitudinal central section of my improved atomizer. Fig. 2 is an elevation showing the atomizer telescoped, the receptacle being indicated Wit-hin the bulb in dotted lines. Fig. 3 is a plan, upon an enlarged scale, of the nozzle 5. Fig. 4 is a plan view of a cross-section on line A A of Fig. 1, enlarged. Fig. 5 is a plan view of a crosssection on line B B of Fig. 1.l Fig. 6 is alongitudinal central section of a simpler form of my improved atomizer. of a cross-section on line C O of Fig. 6.

The object of my invention is to produce an atomizer which shall be portable, of few parts, and so constructed that it maybe held in one hand to operate, leaving the other hand free.' My atomizer employs a bulb of the ordi-y nary Davidson type, as is common in all atomizers, the bulb having a check-valve for the admission of air. Fitting into the opposite end of the bulb to that in which the checkvalve is iixed is a receptacle which has a sliding engagement with the bulb and may be pushed within the bulb or withdrawn from the bulb, but still remain in engagement therewith in telescoping fashion. This slidling receptacle is marked 3, and in Fig. 1 it is shown as having double walls, the inner wall being marked 4, a space being left between the walls when the double-walled receptacle is used. When the double-walled receptacle is not used, as in the simpler form, (shown in Fig. 6,) a passage is formed or secured in the wall of the receptacle, which passage conveys air from the bulb when the bulb is compressed to the upper inner end of the receptacle, where itis discharged. At the upper or Fig. 7 is a plan viewv outer end of the receptacle 3 is secured a spraying device.

The above elements constitute an entirely novel arrangement of the parts to perform the function of an atomizer. I will now describe in detail the construction of my atomizer which is illustrated in the drawings.

At the free end of the bulb 1 is inserted the air-inlet check-valve 2. At the other end of thebulb from that in which the check-valve 2 is inserted and secured is a large aperture, in which is secured a ring of metal or hard rubber 6, to which the edges of the aperture -in the bulb are secured. Within this ring is fitted a telescoping receptacle 3, which has a sliding engagement with the ring 6, and this receptacle is prevented from being drawn through the ring and out of the bulb by an annulus 7 upon the exterior lower end of the receptacle 3; The upper face of this part 7, fitting against the lower side of the ring 6, forms a tight joint when 'the telescoping receptacle is drawn to its full extent out'of the bulb. The upper end of this ,receptacle 3 is closed by the screw-cap 8, having a nozzle 9, the upper end of this nozzle having a minute passage 10 for the escape of the atomized liquid.

`The screw-cap 8 of the receptacle 3 has secured to its under side, in what I consider its best form, an innerwall 4, of glass, hard rubber, or the like. Within the nozzle 9 is secured a pipe 11, which terminates at its upper end in the conical nozzle 5, having small grooves 5 upon its outer surface, while the lower end of the pipe is within the receptacle. The conical nozzle 5 tits into a counterpart conical seat at the upper inner end of the nozzle 9, and a small aperture 12 at the apex of thevconical nozzle 5 permits the escape of iiuid passing through the pipe 11 through the aperture 12, registering with the aperture 10. A passage 13 through the bottomv of the receptacle 3 allows air to pass from the bulb 1 into the upper interior of the receptacle 3, and when the inner wall 4 is used another passage 14 permits air to pass from the space between the The inode of operation is identical in both Walls of the receptacle through screw-cap S to the upper interior end of the receptacle 3, above the upper end of the inner Wall 4.

The operation of the device is as follows: The telescoping receptacle having been pulled out to its full length, part 7 forming a fluid-tight joint with the ring 6, the bulb 1 is compressed, thus forcing lthe air therein coni tained into the interior of the receptacle 3,

creating a pressure of air within the receptacle,which presses upon the surface ofthe liquid contained therein, simultaneously tending to force the liquid contents through the pipe 11, and at the same time forcing a blast of air through the grooves 5a to unite with V forms of my atomizer.

When the atomizer is not in use, the recep` tacle 3 is pushed back into bulb l, and acap 15 may be placed over the nozzle 9 to prevent the escape of the liquid contents of the receptacle. The 'receptacle in the mouth of the bulb may begiven either a fixed engagement therewith, or, in what I consider a better form, a telescopin g engagement therewith by means of which when the atomizer is not in use the atomizer may be pushed within the bulb.l

I claim-V 4l. An atomiz'er made up of a bulb; a receptacle fitting into the mouth of the bulb and having a sliding engagement therewith and a passage through its walls communicating at the lower end of the receptacle with the interior of the bulb and opening at its upper end into the upper interior portion of the receptacle to permit the passage of air under pressure from the bulb to the upper interior end of the receptacle when the bulb is compressed; and a spraying device at the free end of the receptacle, having a pipe depending within the receptacle.

2. An atomizer made up of a bulb; a double-walled receptacle, having a space between the Walls and an aperture through the outer wall at the lower end thereof and an aperture through the inner Wall at the upper end thereof; a spraying' device at the mouth of the receptacle, having its liquid-pipe depending within the inner Wall of the receptacle; all organized and arranged, substantially as shown and described, to permit the passage of air under pressure from the bulb to the upper interior end of the receptacle, when the -bulb is compressed.
